Project that exhibits the error.

1) Open attached project.
2) Open NewJFrame1.java
3) Move jList1 up just a bit until it snaps to the "large preferred distance" of the component above without snapping to any guideline on the left side. See attached screenshot for position.

This AssertionError occurs.

Screenshot of action.
Comment 4 MackSix 2011-10-15 06:52:41 UTC 
If snapped to the left side of jScrollBar1 at the same time as the above placement, a different AssersionError is thrown.
Comment 5 Jan Stola 2011-10-19 13:04:07 UTC 
Fixed - the mentioned exceptions are no longer thrown.
